What should I pay attention to when changing oil

1. Pay attention to the oil change time.The oil change cycle needs to be judged according to your own car habits. If you drive for a long time, you can replace it in advance. If the vehicle is only used for transportation, you can slow down the replacement time. In synthetic oil, it is recommended to replace semi-synthetic oil at 8,000 kilometers, while in synthetic oil, it can be replaced at 10,000 kilometers or once a year.

2. Choose the right oil. When choosing the right oil, you need to choose it strictly according to the oil level specified in the instruction manual. If there is no oil of the same level, you can only use a higher grade of oil, and never replace it with a lower grade of oil. At the same time, you should pay attention to whether the viscosity of the oil meets the requirements, and don't have the idea of choosing the right one.

3. Different oils cannot be mixed: If the medium and high-end oil is replaced with ordinary oil, the original oil should be cleaned first, and the lubrication system should be cleaned. Do not be mixed.

4. Check the shelf life of car oil. The easiest way to check the shelf life of car oil is to observe whether the viscosity of the oil changes, judge whether the smell of the oil fades, and observe whether the color of the oil changes. Among them, when observing the change of oil color, pay attention to the change of additives in the oil.

Step 2: Place the old oil container under the oil span, find the oil release bolt of the oil sup, slowly unstw the open oil bolt, and be careful not to touch the hot oil.
